Abstract: A shift-by-wire system improves responsiveness to a shift command and ensures safety. An electric motor generates a rotational output to be used to switch the ranges of an automatic transmission. A by-wire control circuit unit electrically controls the rotation of the electric motor to comply with an inputted shift command. If a re-shift command is inputted during switching control, the by-wire control circuit unit modifies rotation control. The modification can be implemented until the rotational position of the electric motor reaches a new target rotational position to comply with the re-shift command.

Abstract: An ECU controls a starter relay. Output angle detector detects a rotational angle of an output shaft in a rotary actuator. The ECU stores a first rotational angle which is detected by the output angle detector when a starting switch is OFF. When the starting switch is ON and when the difference between a second rotational angle detected at that time by the output angle detector and the first rotational angle already stored is not within a certain value, the ECU inhibits the operation of the starter relay to inhibit engine start.

Abstract: An SBW storage of an SBW controller stores a rotational angular position of an output shaft of an electric actuator. When the SBW controller is restarted due to instantaneous power interruption, the SBW controller maintains and uses the current angular position of the output shaft, which is stored in the SBW storage device, as a latest rotational angular position of the output shaft that is used to drive a shift range change mechanism upon satisfaction of the following conditions: the electric motor has not been driven before the instantaneous power interruption, and the current rotational angular position of the output shaft, which is stored in the SBW storage device, is not destroyed.

Abstract: A position shift control apparatus is provided which includes an electrical motor joined to an object through an output shaft and a torque transmission mechanism, a detent mechanism producing elastic pressure to hold the object at a target position, and a motor controller. When torque, which is created by the elastic pressure produced by the detent mechanism and acts on the output shaft during rotation of the motor, is opposite in orientation to that outputted by the motor, the motor controller determines the angular position of the motor, as sampled upon a change in an output from an output shaft position sensor, as a reference angular position of the motor for use in controlling the position of the motor, thereby resulting in a decrease in mechanical load on the detent mechanism and the torque transmission mechanism to ensure the durability and operation accuracy of the apparatus.

Abstract: A controller determines the state of the range detector on the basis of the detection signals detected by the range detector, then when the range detector is determined to be in an abnormal condition, the controller moves the shift-changing valve until the movement is inhibited by the restriction member, thereby establishes the position of one end, and controls the actuator with respect to the established one end position and on the basis of the amount of operation to move the shift-changing valve to the position corresponding to an instructed shift range. Even when the range detector is in an abnormal condition, it is possible to make a change to the shift range corresponding to a shift range changing command.

Abstract: By utilizing a mechanical backlash generated between an electric actuator and a shift range switching mechanism, a specific region is obtained, in which a variation in the output shaft angle is relatively small with respect to a variation in rotor angle. In this specific range, an actual shift range position is calculated, whereby the rotor angle that the motor controller recognizes is corrected so as to relate the actual shift range position. A deviation between the rotor angle and the actual shift range is corrected, so that the shift range switching is precisely performed.

Abstract: A synchronous motor controller is provided which is designed to diagnose whether a failure is occurring or not in energizing one of phase windings of a synchronous motor which is required to be energized first to start the synchronous motor. When such a failure is found, the controller reverses the synchronous motor slightly to bring one of the phase windings which is possible to energize properly to a starting position where the energization of the phase windings is to be initiated to start the synchronous motor in a required direction, thereby ensuring the stability in starting the synchronous motor even if any of the phase windings is failing to be energized.

Abstract: When a detent plate reaches a drive/control stopping position, the torque reducing control for gradually reducing electric power supplied to an electrically operated actuator by duty control is performed and then energizing the electrically operated actuator is stopped. With this, the output torque of the electrically operated actuator is gradually reduced and even when the drive/control stopping position deviates from a detent stabilizing position, the balance between drive/control stopping torque and restoring spring force is gradually released and hence the detent plate does not swing after switching the shift range is finished.
